2o6 . CRETACEOUS PALEONTOLOGY. 



Description. "Test elongate, straight, tapering sharply; sur- 

 face smooth; nine oval, regular chambers, rapidly increasing in 

 size toward the distal end ; primordial end acuminate ; ultimate 

 chamber globose, anteriorly prolonged into a distinct eccentric 

 tube; septa depressed, transverse; aperture nipple-shaped. 



"Length, 0.9 mm." (Bagg.) 



Remarks. "The above species is very similar to Dentalina 

 subrecta Reuss, but the latter has fewer segments and the proximal 

 end less acuminate." (Bagg.)

Description. "Test composed of six or seven short, oval cham- 

 bers, very strongly separated by septal constructions. The an- 

 terior portions of the ultimate chambers are smooth, but upon the 

 lower ends of these are two rows of spines or tubercles jutting out 

 at a low angle from the surface. Upon the primordial segments 

 these spines are found to. cover the whole surface. Primordial 

 chamber armed with a short spine ; ultimate segment ending in a 

 tubular neck, which carries the round aperture.
